G&K not there.

I've been playing BNW and I don't like all of the popularity business so I want to go back to G&K but it does not show up as a separate title, and when I click on Civ5 I keep getting BNW

Any ideas?

Go the main menu, click the DLC button and deselect BNW. Then start a new game. You will have to do this each time you restart Civ V if you want to play G&K.

Alternatively, you can go to your Steam Library, right click Civ V, choose Properties, and then go to the DLC tab and deselect (uncheck) BNW. That will uninstall BNW; you can reinstall it any time the same way (check the BNW box in the DLC tab).

Thanks
